Introduction: Chronic unimanual motor practice increases the motor output not only in the trained but also in the nonexercised homologous muscle in the opposite limb. We examined the hypothesis that adaptations in motor cortical excitability of the nontrained primary motor cortex (iM1) and in interhemispheric inhibition from the trained to the nontrained M1 mediate this interlimb cross education.
Methods: Healthy, young volunteers (n=12) performed 1000 submaximal voluntary contractions (MVC) of the right first dorsal interosseus (FDI) at 80% MVC during 20 sessions.
Although there is consensus that the central nervous system mediates the increases in maximal voluntary force (maximal voluntary contraction, MVC) produced by resistance exercise, the involvement of the primary motor cortex (M1) in these processes remains controversial. We hypothesized that 1-Hz repetitive transcranial magnetic stimulation (rTMS) of M1 during resistance training would diminish strength gains. Forty subjects were divided equally into five groups.

- The study aimed to investigate whether transcranial magnetic stimulation (TMS) affects the blood-brain barrier in depressed patients using magnetic resonance imaging.
- TMS is a noninvasive technique for stimulating the brain, although its mechanisms are not well understood and there are concerns about safety related to brain diffusion changes.
- Ultimately, the results showed no significant differences in brain diffusion before and after TMS, suggesting that the treatment does not lead to harmful changes in the blood-brain barrier.
